The video was revised in August 2018 following the comments made by Mr. Chris Langille at Univ. of Western Australia on units and numbers.

Based on the cooperation between Prof. Seokwon Jeon from Seoul National University(South Korea) and the ISRM Commission on Testing Methods, video films on the ISRM Suggested Methods, which are made for educational purpose, will be embedded in the Commission’s website. It is an attempt by the Seoul National University to provide detailed explanations on the ISRM Suggested Methods. The video films are being recorded from the experiments conducted in Rock Mechanics and Rock Engineering Laboratory, Seoul National University. New video films on other Suggested Methods will also appear in the website in near future.
